Syria guilty of "industrial-scale killing," says Qatar-backed report

Three former international prosecutors have accused Syria of large-scale killing and torture in a report - based on evidence of a defector - commissioned by Qatar, which backs Syrian rebels, the Guardian and CNN reported Monday.

The report, which can be found online at both news outlets, relies on the unauthenticated testimony and photographs given by the source, who remains unidentified for security purposes. (AFP)
